Correct answer: B

  1. Understand the question

    Ionic reactions in organic chemistry involve the formation of ions as reactive intermediates.

  2. Type of bond cleavage in ionic reactions

    A covalent bond can break in two ways:

    • Homolytic cleavage: each atom takes one electron A−B→A∙+B∙A-B \rightarrow A^{\bullet} + B^{\bullet}A−B→A∙+B∙ This produces free radicals.

    • Heterolytic cleavage: one atom takes both bonding electrons A−B→A++B−A-B \rightarrow A^+ + B^-A−B→A++B− This produces ions.

    Since the question asks about ionic reactions, they proceed through heterolytic bond cleavage.

  3. Check each statement

    • (A) homolytic bond cleavage: incorrect for ionic reactions
    • (B) heterolytic bond cleavage: correct
    • (C) free radical formation: incorrect, this is typical of radical reactions
    • (D) primary free radical: incorrect
    • (E) secondary free radical: incorrect

  4. Match with given options

    The correct choice is (B) only, which corresponds to Option B.

  5. Comparison with stored answer

    Stored correct answer: B

    Derived answer: B

    Hence, the derived answer agrees with the stored answer.
